Knowing the mouse might one day find a way to heat up the spaghetti... It fills you with determination.

It's a plate of lukewarm spaghetti. Seems like something tried eating it and just... Gave up.[True Pacifist Ending Epilogue]

Snowdin - Dog House (room 61: room_tundra_lesserdog)

Snow can always be broken down and rebuilt into something more useful. This simple fact fills you with determination.

The thought that one day the dog will create the perfect snowdog fills you with determination.[If the protagonist petted Lesser Dog 3 or more times]

Snowdin - Town (room 68: room_tundra_town)

The sight of such a friendly town fills you with determination.

On the Genocide Route, all Snowdin SAVE Points read "That comedian..." after arriving in Snowdin. The comedian is not Sans, as some mistake it to be, but Snowdrake, as confirmed by SAVE Points when sparing him: "The comedian got away. Failure." If the protagonist reaches Papyrus and defeats him without exhausting the kill count, the SAVE Points return to their usual state and a Genocide Route is aborted.

The waterfall here seems to flow from the ceiling of the cavern... Occasionally, a piece of trash will flow through... and fall into the bottomless abyss below. Viewing this endless cycle of worthless garbage... It fills you with determination.

Partaking in useless garbage fills you with determination.[If the protagonist has already interacted with the SAVE point once]
